No UI shown, though the process is running in background.

 I build a dll using error detection with coverage analysis. Now this dll is loaded dynamically in an MFC app.

I run the following command to capture code coverage for the dll.

 

dpanalysis.exe /cov /output test.dpcov /p mfcapp.exe

 

Now mfcapp.exe is launched and is running, but no UI is shown. If i do not instrument the dll, the UI of mfcapp .exe is shown but ofcourse i can't do the coverage then. Any ideas what could be wrong?
